Question 5. Global Positioning System (GPS) satellites emit a signal in the form of pulses of electromagnetic radiation at fixed intervals. A particular GPS satellite orbits at a fixed height of 20 200 km above Earth's surface. The frequency of the radiation that the satellite emits is 1 575.42 MHz. The wavelength of this satellite's signal is A. 1.90 x 10-7 m B. 0.190 m C. 5.25 m D. 5.25 x 10 m Question 6. Use the information from question 5. The time required for a signal to travel from the satellite to an object on Earth directly below the satellite, expressed in scientific notation, is a.be x 10's. The values of a, b, c, and d are and 9 (Record all four digits of your answer in the numerical-response section on the answer sheet.)
